摘要 为解决虚拟样机模型与物理样机实际模型的一致性校准问题,运用多体动力学理论及Adams/Car软件搭建了某新能源车辆的悬架系统动力学模型,同时在悬架系统平行跳动及侧倾跳动工况输入下完成了悬架系统的K&C运动学分析。根据现有某企业标准在同样工况下完成实车的客观测试,将数据展开深度解读和关联后,完成了仿真模型的调试校准,对仿真模型的精准度做了优化提升。研究表明,该新能源车辆仿真模型与实际车辆模型对标结果的平均关联度为91%,利用该仿真模型可进一步完成整车虚拟样机的仿真测试,对底盘行驶性能的前期设计及后期优化有重要的工程指导意义。 In order to solve the problem of consistency calibration between virtual prototype model and physical prototype model,this paper uses multi-body dynamics theory and Adams/Car software to build a suspension system dynamics model of a new energy vehicle.At the same time,K&C kinematics analysis of the suspension system is completed under the input of flat jump and roll conditions of the suspension system.According to the existing standards of an enterprise,the objective test of the real car under the same working conditions was completed.After in-depth interpretation and correlation of the data,the debugging and verification of the simulation model was completed,which optimized and improved the accuracy of the simulation model.The research shows that the average correlation between the new energy vehicle simulation model and the actual vehicle model is 91%,and the simulation test of the vehicle virtual prototype can be further completed by using the simulation model.It has important engineering guiding significance for the early design and later optimization of chassis driving performance.
